I was researching the Toyota Prius and stumbled upon the fact that there is up to a $3400 tax credit next year for if you purchase and use a hybrid vehicle this year. Note, this is next year’s filing. You should buy earlier. This only applies to the first 60,000 of each model hybrid any particular company sells. There is a tax incentive for last year, but you must have purchased your vehicle by 12-31-05.
